*Added light near gel drop portal to enhance its visability from gel enabling button.*Moved power "antlines" of the two cube drop fizzlers connected to the standing button to the right to make them more visible to the player.

*Added grate above gel panel to prevent bouncing on the panel to get to fizzler-disabling platform.*Removed portal surfaces near cube buttons which could allow for a very skillful use of the lightbridge in which you could skip everything in the map.*Moved cube drop and fizzlers below one square back to prevent unintended solution to puzzle in which player would catch the cube before it hit the lowest fizzler.

*Added partial glass wall to fizzler-disabling platform to fully prevent use of the light bridge to get on the platform.*Added assistive lighting.*Moved gel button to right so it would be easier to see target portal areas.*Added some portal surfaces for visual touch.

*Removed portal surfaces which could unintentionally be used to bounce up to fizzler-disabling button.*Added fizzler and grate to gel button so player cannot put gel onto light bridge which could lead to skipping a portion of the test chamber.*Moved gel button to allow for greater visibility of target portal area.
